In the sintering production in order to ensure the continuity of production and operability , and out of the raw materials and intermediate process , set up many intermediate mine shafts , mine slot was material control is sintered material balance control . The idea is that the material balance in the continuous production process of the entire sintered ensure demand and consumption are equal , thereby maintaining the balance of material level . In this paper, the basis of analysis of the mechanism of the sintering process for the sintered material balance control difficulties , proposed material balance control strategy and control system configuration . Different mine shafts in the sintering process control , process equipment using different control strategies . On BEDDING material ore tank material level , ring cooler unloading control of the mine shafts , feedforward plus feedback , feedback correction with a dead zone PI operation ; ingredients mine shafts material level detection , translation management to be based on material bit different detection methods , the level of the alarm processing ; backward ore trough material level control mixing ratio by dynamically modifying control high capacity to achieve the balance of the back to mine ; to mix ore trough level control , data track mobile and data tracking technology, the raw material on the conveyor of the material handling system , their sum , as into the grooves the amount of ( Win ) , the discharge amount of mixed chute (Wout) computing , according to Win, Wout, and mixing chute material level deviation for the weight of the balance of payments calculus , and then mixed trough material level control by changing the consolidated throughput . Material balance control in the sintering process in the entire sintering process control with basic automation level (L1 ) and optimization of the control level (L2 ) material balance , in order to achieve a material balance control , hierarchical control system structure . Required in the system hardware and software, the completion of the data flow design of the material balance . Through the practical application of the material balance control system sinter plants in the iron and steel enterprises , sintering production process to achieve a material balance of the whole process , to ensure the stability of the sintering process , to improve the economic efficiency of enterprises .
